Quizplus · Accepted Answer

All of the above options provide evidence that animals learn to expect a certain type of reinforcer in an operant conditioning situation. In option A, the association of one of the reinforcers with poison shows that animals have learned to expect a certain outcome based on the type of reinforcer used. In option B, satiating the animals with one of the reinforcers shows that they learn to predict which reinforcer they will receive and may become less motivated to perform the associated response if they receive too much of it. Finally, in option C, the animals looking "surprised" when the type of reinforcer is changed suggests that they have developed expectations about the consequences of their responses and are surprised when those expectations are not met.
